Beast Attack in Adonisjs (Typescript)

To mitigate BEAST risk in an AdonisJS application using TypeScript, enforce TLS 1.2 or higher at the server level. Since AdonisJS uses the @adonisjs/core framework, TLS configuration typically occurs in the server.ts file or via environment variables passed to Node.js. Use TypeScript interfaces to define and validate secure TLS options. Example:

// start/server.ts
import { HttpServer } from '@adonisjs/core/http'

interface SecureTLSOptions {
  minVersion: string;
  ciphers: string[];
  honorCipherOrder: boolean;
}

const tlsOptions: SecureTLSOptions = {
  minVersion: 'TLSv1.2',
  ciphers: [
    'TLS_AES_256_GCM_SHA384',
    'TLS_CHACHA20_POLY1305_SHA256',
    'TLS_AES_128_GCM_SHA256'
  ],
  honorCipherOrder: true
};

// Validate at runtime (optional but recommended)
if (!['TLSv1.2', 'TLSv1.3'].includes(tlsOptions.minVersion)) {
  throw new Error('TLS version must be 1.2 or higher')
}

await HttpServer.createInstance()
  .listen({ host: '0.0.0.0', port: 3000, tls: tlsOptions })

Alternatively, rely on secure defaults by ensuring Node.js is updated (v12+ disables TLS 1.0/1.1 by default) and avoid explicitly setting insecure minVersion. Use helmet middleware via AdonisJS hooks to set secure headers, though this does not fix TLS version. middleBrick’s Encryption check will flag TLS 1.0 support; remediation requires server or infrastructure-level changes, not application logic alone. Always verify with a rescan after updating Node.js or reversing proxy configurations (e.g., Nginx, Cloudflare) to ensure TLS 1.0 is disabled.
